DISTRIBUTIVE DEPOSITING OR PANNIN'G MACHINE.

SPECIFICATION forming part of Letters Patent `N' o. 684,789, datedOctober 22, 1901. Application filed December 30, 1899. Serial No.742,121. (No model.)

T0 @ZZ wir/0711, it' may concern:

Be it known that I,LOUIS S. BURBANK,a citizen of the United States,residing at lVorcester, in the county of Worcester and State ofMassacl1usetts,have invented certain new and useful Improvements inDistributive Depositing or Panning Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

In the accompanying drawings, Figure 1 is a side elevation of mymachine. Fig. 2 is a plan view of the same. Fig. 3 is a front elevationof the same. Fig. 4 is a section on the line 4 4, Fig. 2; and Fig. 5 isa detail view illustrating the adjusting mechanism for thedepositing-lip.

The object of the invention is to provide a machine for depositing inregular order and in parallel rows upon pans or receivers sections orcakes of shredded wheat or other preparations for cooking and for suchother purposes as it may be found useful; and it consists in the novelconstruction and combinations of devices, as hereinafter set forth,

In the accompanying drawings, illustrating this invention, the letter Adesignates the main frame of the machine, and B a pulley having itsbearings therein near one end, its shaft?) projecting for theapplication of power. Around the pulley B passes one end portion of acarrier-belt D, which extends horizontally along the frame and passesaround the small end pulley c and below and around the takeup pulley Eand the tension-pulley F, the latter being also connected to the mainframe of the machine, an adjustable bearing f being provided for thcpurpose. The pulleys c and E are mounted in bearings of a reciprocatingcarriage G, the operation of which is designed to alternately shortenand lengthen the carrying portion of the belt D', so that While thereceiving portion of this belt moves along continuously and steadilywith the sections of biscuit or cakes deposited thereon the other endportion of the belt shortens and lengthens itself alternately, by theone movement depositing the biscuit-sections upon the receiver or pan Zand by the other movement carrying forward the line or feed ofbiscuit-sections to be deposited in the second row upon Said receiver orpan parallel to the first row, a lateral adjustment and longitudinalretraction of the receiver or pan taking place While the depositing-beltis lengthening. The reciprocating carriage G is geared to moveat thesame rate of speed as the pulley B and as the reciprocating carriage Nof the receivers or pans.

The main frame is provided with slidcways I for the carriage G, to whichis connected the small end pulley c and the intermediate pulley E, whichwhenl the delivery portion of the belt is retracted by the backwardmovement of the carriage G also moves backward and serves as a take-upfor the shorteningbelt.

M indicates a reversing-shaft having a pinion m, which engages by itsupper portion the rack g of the beltcarriage G and by its lower portionthe rack n of the carriage N of the pans or receivers. By means of thispinion and, a reversing-shipper, in connection with fast and loosepulleys at Z, these carriages are reci procated in opposite directions,

but at the same rate of speed.

The carriage N of the receivers havingthe lower rack n carries thesprockets of the chains S, upon which the receivers or pans are placedin position to receive the biscuitsections from the depositing portionof the belt D. The sprocketv chains run transversely, and they areprovided with guidestuds s, placed at proper intervals to insure thecorrect position of the pans when laid on said chains. The operation ofthese sprocketchains by means of slide-shaft s', its pawl device r, andthe cam .l serves to give the proper intermittent lateral movement tothe receivers or pans. This lateral movement is effected as the carriageis moving backward, the slide-shaft of the sprockets during thismovement moving its pawl device or disk along the camway R', so that oneof its pawls r engages the spiral cam-rib R, turning said shaft. Duringthe forward movement of the carriage the pawl r passes loosely over thecam-rib ,so that there is no engagement therewith, and the pan on thecarriage moves in a direct line.

At the end of the carriage G is provided a depositing lip or slide V,which takes the biscuit-sections from the end ofthe carrier-belt D andpasses them down its incline to the receiver. By means of suitablegearing (indicated at c and w and operating in connection with thereversing mechanism) this depositing-lip is raised at the end of themovement of delivery and held in the raised position until the extendedbelt D is ready to place another row of biscuit-sections on thereceiver, when said lip is lowered promptly to inclined position and soheld until the delivery of this row is completed. The movement ofreversal of the depositing-lip takes place at the time of the movementof reversal of the carriages, and is effected by the same reversingdevices. A sleeve-screw c' in connection with the threaded end of therod w serves to change the relative position of said worm, so that anadjustment of the degree of inclination of the depositing-lip lnay bereadily effected while the machine is in motion. The reversing mechanismis operated automatically by the carriage G through its lugs Z and Z',which alternately engage a boss l" of the switch-lever P. The lugs Zandl are slides which are adjustableon a longitudinally-adjustable bar atthe side of the carriage, which serves as a bearing for said lugs, beingengaged by longitudinal channels in the bottoms thereof. These lugs whentheir adjustment is fixed on this bar are conjointly adjustable by meansof a rightand-left screw b, engaging a threaded lug of said bar. Aseither or both lugs are therefore adjustable, means are provided forlengthening or shortening the stroke or varying its position. Theseadjustments are important in arranging the terminal position of thereceiver-carriage as well as that of the delivering-lip ot thecarrying-belt with reference to the positions of the biscuit-sections.The switch-lever P by means of the slide p' actuates the reversing-beltsof the fast and loose pulleys and also operates thereversinggear of thedelivery-lip. The biscuit-sections being fed in regular succession uponthe belt D are by means of its reciprocating end portion and thedepositing-lip placed upon the receiver or pan, the operating mechanismof which by effecting arl-intermittent lateral movement of said receiveror pan serves to produce an arrangement of the biscuit-sections inparallel rows thereon. As one pan is lled another pan is placed upon thecarriage to be lled. Usually the receiver-carriage is made wide enoughto hold two or more pans side by side in order to give the attendanttime enough to remove a filled pan and to place an empty one upon thesprocketbelts while an intermediate pan is being filled.
